Hi guys;
I'm working on a 420 that has been repowered with a P220 Onan that my friend just picked up.
I decardoned the heads, new plugs, wires, and installed a new Carb. The new carb works great and it runs perfect.

The problem is I have no governor. The arm moves freely.
When you move the throttle lever open just about 1/4" it revs way to high to fast. If I went all the way up it would over rev the engine.
What do you think is the problem? :dunno:
Any help would be much appreciated.

Does someone have a picture they could post of the governor and linkage on theirs that is installed the way it should be?

in the jd sticky section there is the onan manual and it should be in there.

Thanks Boomer. I hope its an easier fix than that. I don't want to remove the engine.

Ok. The manual said hold the governor arm all the way back and the arm on the carb and see what holes line up best with the linkage rod.

I did what it said. I noticed the new carb has two holes on the carb arm. I moved it to the back one and fixed. Purrs like a kitten!

Praise God it was an easy fix! All of 3 minutes and I was in business.
Thanks Boomer and smithrngr for the suggestions. :thanku:
